Be it known that 1, JOHN LoU'Is BUR; GOYNEi-tt citizen of: the Un1ted-States and a resident'of 'the city and-county'ofSan Fran i cisco, State of California; have made a new W'orkin-g and Shaping Dough or othen Plas-" tic Substances; and I do hereby*dec1arethe following to be a full, Clea-1"; concise, and ex act descriptionthereof:

A series of in the side walls '1 so ,1 thatthe tool '10 may be adjusted to different ticalpositions' and to arious angles with relation as the oonveyer belt and] held in such positions by the side walls 7 when drawn'inwaidlji against the tool by the bolts 11 and the nuts At of the tool 10 is formed surface" 15, whiclfsurfaoe is preferably, of

the lower portion "conve'tf shape and leads fron the i'eai ofthe tool forward yfto an edge 16 at the lower- In, most extremity of the'it'i'ontface of the tool.

The sii'ifeee l5 and the belt 4 converge forthe otherfpressure wardly toward each other, so as to work the dough as it passes therebetween and so that the dough will be rolled at the edge 16 as will be hereinafter more fully described. An idler 20 is journaled in arms 21 fixed on shaft 22 which shaft is mounted in hearing 23 in the side walls 7. Said idler may be swung into engagement with the belt 4 to tighten the belt by turning the shaft 22. The idler may be secured in different positions with relation to the belt by a set screw 24, which screws into bearing 23 and en gages the shaft 22 and holds the shaft against turning. Located above the rear end of the conveyer 1 is a flour sieve 25, the lower wall 26 of which is perforated so that the flour in the sieve may drop through said wall onto the conveyer. A rotary brush 30, fixed on a shaft 31 journaled in the side walls of the sieve, is located within the sieve and is adapted to sweep 1 the perforated wall 26 and force the flour brush may be rotated from the shaft 5 through the medium of pulleys 43 and 44 and belt 45 which travels over said pulleys.

An inclined apron 48 may be placed in front of the pulley 3 to convey the dough away from tie machine after it is operated on by the machine.

Power may be applied to the shaft 5 to drive the conveyer 1 in any suitable manner, as for example, through the medium of a pulley 50 on shaft 5 and belt 51 which travels over said pulley, or the machine may be hand-driven by a suitable crank or otherwise.

The operation of my invention as herein disclosed. is as follows: The pulley 3 is rotated in the direction of the arrow (4 by power through the medium of belt 51, pulley 50 and shaft 5, which causes the belt 4 to travel in the direction of the arrows b and c and the pulley 2 and shaft 5 to rotate in the direction of arrow (Z. 'As the shaft 5 is so rotated, the sieve brush 30 is rotated through the medium of pulley 33, belt 35, pulley and shaft 31, which brush sweeps the'flour in the sieve through the perforated wall 26 thereof onto the rear portion of the belt 4. As the sieve is operated and the flour sifted therebyupon the belt, the brush 0 is rotated in the direction or arrow 6, from shaft 5 through the medium of pulley 43, belt 45, pulley 44 and shaft 41, and the excess flour is swept from the belt by the brush into the pan 42. The flour which is swept into said pan may be placed in the sieve and used over again.

A lump of dough D is placed upon the belt and is carried forward thereby so that it first engages the surface 15 of the tool 10 as indicated in Fig. 13 of the drawings. As soon as the dough engages the surface 15, as indicated in Fig. 13, the forward movement of the belt continues to carry the dough forward and causes the dough to be compressed between the surface 15 and the surface of the belt as shown in Figs. 14 to 17 inclusive, whereby the dough is worked so thatit is kneaded and gas is pressed out of it. When the dough is carried by the belt under the edge 16 of the tool, said edge scrapes the upper side of the dough and draws it out into flat form having an adhesive surface on said upper side which surface adheres to the tool edge 16 and retards the movement of the upper side of the dough, while the flour on the belt forms a non-adhesive surface or skin on the lower side of the dough. As the belt pulls the dough forwardly under the tool edge 16 and said edge retards the upper side of the dough by its adherence to said side, the under non-adhesive or skinside of the dough is caused to roll upwardly against thev front face of the tool and upon the adhesive upper surface of the dough,as illustrated in Figs. 15 to 18 inclusive, until the dough is completely rolled with its adhesive surface inside the roll, as shown in Fig. 18 of the drawings. The dough when completely rolled by the belt and tool edge is given a substantially straight key or seam extending longitudinally of the roll, as shown in Fig. 20 of the drawings. The rolling of the adhesive surface of the dough inside the dough roll causes the layers of the dough to adhere immediately together and to integrate so as to form a substantially homogeneous mass, as shown in Fig. 24 of the draw ing, having the outside of the roll non-act hesive and of skin-like formation.

When it is desired to roll the dough into,

slightly in the rear of pulley 3, as shown in full lines in Fig. 1 of thedrawings, in which position the belt 4 bellies slightly downwardly transversely as the dough passes between it and the edge 16, which gives the loaf the proper median diameter and taper toward its ends. By adjusting the tool 10 so that the edge 16 rests directly over the pulley, as shown in dotted lines in Fig. 1 of the drawings, a relatively long French loaf of small median diameter may be rolled. Byadjusting the t-oolso, that the edge.-l6.; rests over thebelt between the pulleys,asv also indicat ed in dotted lines in Fig-.1 of the drawings, the belt will belly considerably downwardly transyersely, as shown in; Fig-P21 of the.;drawings, and cause the dough to berolled.into,a relatively ShOI'l'm'. Fren'clrloaf of large ,median .d-iameter as shown in Fig.22 ofthedrawings. e

VtThen the tool isadjusted sothatthe edge 16 rests, over the beltbetween the .pulleys,- the shape of the loavesmay be yaried by adjusting the tension of the conveyer belt. By increasing the tension ofthebelt a rela i' ti'vely long loaf of, small median diameteris produced. By diminishingthe tension :of' the belt a relativelyshortloaf oflarge dian diameter is produced; I H

The tool edge l6 niay be made straight and the pulley 3 conveXed axially as shown in Fig. 5 ofthe drawings, so as to roll a substantially cylindrical or; American loaf as shown in, F ig 23 of the drawings. The tool may be made; with a straigh edge 16 and thepulley concaved axially shown in Fig. 6 of the drawings, so as to rolla French loaf similarto that shown in Fig. 22/ 7-, The tool may be made with an outwardly curved edge and the pulley madecylindriw cal as shown in Fig. 7 of the drawings so to roll an American loaf similar to-that shown in Fig. 28. I y The tool edge and the pulley may be otherwise constructed and arranged as suggested, for examplein Figs. 8 to 12 inclusive,- to roll the dough as desired. a

Thetoolmaybe adjusted to various positions with.relation tothe belt and pulley; to meet various conditions arising in the The side walls 7 may be adapt-ed to engage the ends of the dough to determine the; 1" length ofthe loaf. I i

Loaves of various lengths and weights may bev formed on a machine by varying the amount of-dough put intothe'machine. The greater theamount; of dough the longer the loafl and vice .VI S3-r 1 I claim: I e
